SHUTTLE-MOTION FOR LOOMS.

PEGIFICATION forming part of Letters Patent No. 510,830, dated December12, 1893.

Application filed July 31, 1893. Serial No. 481,959. (No model.)

To all whom it may concern.-

Be it known that I, SIDNEY O. BAILEY, of New Bedford, county of Bristol,State of Massachusetts, have invented an Improvement in Shuttle-Motionsfor Looms, of which the followingdescription, in connection with the accompanying drawings, is a specification, like letters and figures on thedrawings representing like parts.

Wooden picker sticks now most commonly in use in connection with rockersadapted to rock on rocker beds are tapered toward their upper ends, andthe sticks at or near their lower ends are bolted to usual feet orrockers, and the lug strap or guide through which it is passed isusually confined to the stick by screws. The holes made in the sticktend to weaken it. I

In my studies to improve that class of picking mechanism wherein thepicker-stick is carried by a rocker adapted to rock on a rocker bed, Ihave devised novel means for connecting or clamping the stick to therocker without the necessity of making a hole in the stick, or ofinjuring the edges of the stick so that the said stick is left incondition to be. used either end up.

In my invention I may use a stick parallelogrammic in cross section, thecross sections of the stick being uniform. I have also combined with ametallic rocker, as described, a lug strap guide, the said guide beingextended up at one sideof the stick, the guide serving as a point ofattachment for the lug strap, thus avoiding the strain of the lug strapupon the picker-stick.

Figure 1 shows part of the front of a loom with part of a picker-sticksupported in ac cordance with my invention; Fig.2 a view looking at theparts represented in Fig.1 from the right. Fig. 3 is a section in theline m Fig. 2. Fig. 4 is a section in the line on Fig. 1; Fig. 5 asection in the line 00 Figs. 1 and 3; Fig. 6 a section in the line aFigs. 1 and 3. Fig.7 shows different views of the rocker; Fig. 8difierent views of part of the clamp. Fig. 9 shows views of the secondhalf of the clamp. Fig. 10 shows the arm to which the lug strap isattached. Figs. 11, 12 and rocker bed or support B for the shoe orrocker 0 being attached to the lay journal by a screw 0'.

The rocker shown consists of a curved shoe 0 having an upright hollowportion 0' open at one side to leave flanges to receive between them andserve as a guide for the half 01 of the stick clamp d, 01', each halfbeing shown in several views in. Figs. 8 and 9. The interior of theupright c of the rocker has a recess 16, see Fig. 7, said recessedportion having a hole 15, the recess being adapted to receive the end ofthe loop-like part4 of the portion dot the stick clamp, to be described,and this portion a has also shoulders, as at 22, see Fig. 7, to supportthe outer side of the part d of the stick clamp. The half or portion dofthe stick clamp shown in Figs. 1, 3 and 8 is represented as a metallicbar made claw-shaped at one side or provided with lips to' embrace oneedge of the picker stick e, said lips being herein shown as notched orcut away at two points, as 2, 3, the notches 2 receiving the sides ofthe looped p t 4. of the half or portion d'of the clamp to be described.The half 02' of the clamp shown in Fig. 9 is composed of an uprightportion having extended from it at right angles a box-like loop 4provided with a threaded portion 5, said upright portion having'at oneside a slot 6, the metal at the interior of the said upright portion andbordering said slot being shown as countersunk to receive the other thanround head 7 of a bolt 8, see Fig. 14, to thus prevent said bolt fromrotation in the slot as the nut 10 cooperating with said bolt, see Fig.5, is being turned on or 0F.

The bar (1 as shown in Figs. 1 to 8, has a retaining leg 12 which ispassed through aslot in the rocker bed B to thus help keep the rocker inplace.

To assemble the parts, the bolt 8 will be put in place in the half (1,the slotted part 13 of the lug strap supporting arm f having at itsupper end preferably a slot 14:, see Fig. 10, will be put onto the bolt,and the nut will be applied and turned until the lug strap arm is firmlysecured in the proper or desired position vertically. The half (Z of thestick clamp will then be put into the box-like loop 4; of the part (1'until the open part 2 comes opposite said loop, and the end of the screw5 will then beput through the hole in the upright portion 0 of therocker, the end of the loop entering the recess 16 of the rocker, seeFig. '7, and the nut 18 will then be caught upon the threaded part 5.The end of the stick may now be put between the clamps and pushed downagainst the heel of the rocker as in Fig. 3, and the nut 18 may then bescrewed home to firmly draw the part d of the clamp toward and into theupright part c of the rocker, the part (l of the clamp resting with itsback against shoulders 22 of the said upright portion, see Figs. 7 and3. The rocker with the stick clamped in place will rest on the bed B,and the lug strap 9 connected with some suitable actuating arm gsuitably moved to throw the shuttle, may be led through the slot 1-1 andabout the stick. The lug strap is not connected with the stick, but tothe supporting arm f, yet the strap may embrace and aid in steadying thestick between its ends.

The modification Figs. 11 to 13 is to illustrate another form of bed androcker, the bed h, see Fig. 11, having a horn h to enter a holein therocker 72?, the horn serving the purpose and being equivalent to thepart 12 in Fig. 3, the stick 8 and its clamping members being otherwisethe same as in Figs. 3, 8 and 9.

By the term straight picker stick I mean a stick of uniform width andthickness, as contradistinguished from a tapered stick.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. The combination with a rocker, composed of a shoe having an uprightarm 0', of a stickclamp composed of a socketed portion to receive andcompletely surround the stick, and a detachable independent bar enteringsaid socketed portion and bearing against a portion of the stick, andmeans to connect the said socketed portion with the said rocker,substantially as and for the purpose set forth.

2. A rocker composed of a shoe 0, and an upright arm 0' provided withflanges and having a hole 15 and a recess 16; combined with astick-holding clamp composed of a socketed portion cl having a loop-likeextension 4 and a threaded portion 5 to enter the hole 15 referred to; anut 18 for said threaded portion 5, and an independent bar cl enteringsaid loop-like extension and cooperating with one edge of the stick,substantially as described.

The rocker consisting of a shoe 0 and an upright arm 0' provided withflanges and having a hole 15 and a recess 16; and a stick-holding clampcomposed of a socketed portion cl having a loop-like extension 4: and athreaded portion 5 to enter the hole 15 referred to, a nut 18 for saidthreaded portion 5, combined with an independent bar d notched as at 2,and entering said loop, the latter engaging said notches, substantiallyas described.

4. The rocker consisting of a shoe 0, and an upright arm 0 provided withflanges and having a hole 15 and a recess 16; and a stick-holding clampcomposed of a socketed portion (1 having a loop-like extension 4 and athreaded portion 5 to enter said hole 15; a nut for said threadedportion 5, and a rocker-bed; combined with an independent bar 61 havingan extension 12 carried below said rocker, the shoe rocking upon saidrocker-bed, substantially as described.

5. A rocker composed of a shoe 0 having an upright arm a; a rocker-bedto sustain the said shoe; a picker-stick clamp composed of a socketedportion having a loop-like extension to embrace and completely surroundthe picker-stick; means to connect the said socketed portion to theupright portion 0' of said rocker, and an independent bar cl enteringthe loop-like extension of said socketed portion between it and saidstick, combined with a lug strap guide connected to the said socketedportion, to operate, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
